The mechanical equilibrium angles for a 156-bp circularized DNA molecule with a 12-bp phasing length between the A-tract portion and a 30-bp test sequence. The test sequence has the B-DNA characters, i.e., zero roll and tilt, 4.68° bending flexibility, 34.45° twist, and 4.338° twisting flexibility, except for a 10-degree kink in the middle. The A-tracts have 4.842° bending flexibility and the same twisting flexibility.
